back during the greater part of labour, and thus maintain the same posture for some time, which must necessarily become irksome and even painful to her. In this country and in Germany the patient is delivered upon a common bed, prepared for the purpose as above mentioned: in England she is placed upon her left side, the nates projecting to the edge of the bed, for the greater convenience of the accoucheur: in Germany, except in Vienna and Heidelberg, where the English midwifery has in great measure been introduced by Boer and Naegelé, the patient is delivered upon her back.[67] In former times the supine posture was also used in this country, but for about a century the position on the left side has been preferred; the patient lies more comfortably to her own feelings; her face is turned from the practitioner who sits behind her, and who, from this posture, is able to examine or to perform any other necessary manipulation without her feelings being annoyed by seeing what is going forward. It is decidedly the easiest position during the last moments of tremendous suffering and exertion; when the presenting part is passing she is not able to exert an undue degree of violence, and from the knees being kept together, there is less danger of the perineum being torn. The left side seems moreover to be the natural position for a woman at the moment of parturition, for if accidental circumstances have occurred, such as sudden labour, &c. by which she is deprived of all assistance at this moment, she will almost invariably be found upon the ground lying on her side supporting herself with one hand. In some cases she will remain during these moments upon her knees, into which posture she has gradually dropped from that of standing: in by far the majority of cases she will take the position upon her side, as above mentioned.
